JavaScript Curry

Many JavaScript curry functions are actually implementations of partial application. This module implements true curry behavior in JavaScript.

True curry behavior means only accepting a single argument at a time and only executing upon application of all arguments. [citation]

curried = curry(function (a, b, c) {
	return a + b + c;
});
curried(1)(2)(3); //6

curriedOne = $curried(1);
curriedOne(2)(3); //6

Reverse Currying is also possible

//verbose
curried = curry(function (a, b, c) {
	return a + b + c;
}, true);

//single argument convenience
curried = curry.r(function (a, b, c) {
	return a + b + c;
});

curried('a')('b')('c'); //'cba'
